Avalokiteshvara, the lord who looks down, is the bodhisattva of compassion, and he is the same figure in Tibet, China, Japan, Korea and Vietnam under names that no longer resemble one another. The atlas keeps him as a single figure because the transmission is documented and continuous, not because the differences are trivial.
The core commitment is a vow: to hear the cries of the world and to decline final nirvana while any being is still suffering. Chapter twenty-five of the Lotus Sutra, the chapter called the Universal Gate, states that he takes whatever form will reach the person who calls, and lists thirty-three of them, including a monk, a king, a child, a naga, a deva, and various female forms. This is the doctrinal hinge on which the later Chinese development turns.
In Tibet he is Chenrezig, the patron of the country, and the mantra Om Mani Padme Hum is his, carved into rock faces, printed on flags and turned in prayer wheels across the Himalaya. The Dalai Lamas are held to be his emanations, which is the basis of their institutional authority.
In China he is Guanyin, one who perceives the sounds of the world, a rendering of an earlier form of the name. In Japan he is Kannon, and Sanjusangendo in Kyoto holds a thousand and one of his images. In Vietnam he is Quan Am. In Korea, Gwaneum.
The Indian cult is attested early and well. Faxian recorded monks making offerings to Avalokitesvara at Mathura around 400, and Xuanzang gave eyewitness accounts of venerated statues in the seventh century. The Karandavyuha Sutra, which is largely about him and is the source of the six-syllable mantra, is dated to the late fourth or early fifth century.
He is male in all of that. What happened next in China is the subject of the next article.
